Cookie policy
Last updated September 24, 2026
This policy explains what kefas.lt stores on your device and why. If the language versions differ, the Lithuanian version prevails.
In short
kefas.lt sets no cookies and uses no advertising or cross-site tracking. We use your browser's storage only for features you use yourself. This storage is strictly necessary for those features, so the law does not require your consent and we do not show a cookie banner.
What we store in your browser
kefas keeps these entries in your browser's local storage:
- kefir.board.filters.v1: your board filters, kept until you clear them;
- kefir.bankroll.v1: the bankroll used for stake suggestions; when you are signed in, it is also saved to your account;
- kefir.alerts.seen.v1: the alert matches you have already seen, up to 1000 IDs;
- kefir.bets.settledSeen.v1, followed by your user ID: settled bets you have already been notified about;
- kefir.hidden-lines.v1: prices you have hidden for a while; each one reappears after 10 minutes;
- the Firebase Authentication session: IndexedDB or local storage entries whose names start with “firebase”. They keep you signed in until you sign out.
Analytics
PostHog, which we use for product analytics, is set up to store nothing on your device. It keeps its data in memory only, so every visit is a new anonymous session until you sign in. Vercel Web Analytics does not use cookies.
Third-party pages
Google's sign-in window and Stripe's checkout page run on their own domains. They may set their own cookies, which are covered by Google's and Stripe's own policies.
How to control storage
You can clear the site data of kefas.lt in your browser settings at any time. This resets your filters and bankroll on that device and signs you out.
Changes
If we ever add cookies or other storage that is not strictly necessary, we will ask for your consent first. Changes to this policy are published on this page with the date.
